A single use setting tool for actuating a tool in a wellbore may include an outer sleeve and an inner piston received within a central bore of the outer sleeve. The inner piston may define one or more elongate bores therethrough that are in fluid communication with a cavity of the inner piston and extend axially through a distal end portion of the inner piston. The distal end portion of the inner piston may abut a shoulder of the outer sleeve, for example at a distal end face of the inner piston.

The disclosure of this application is directed to a downhole tool comprising a central element/member and a sleeve that is rotatably and orbitally disposed around the central element/member. The sleeve rotates and orbits around the central element/member responsive to fluid flowing through the downhole too. The disclosure is also related to a method of advancing the downhole tool in a well by flowing fluid through the tool.

An apparatus for remote actuation of a downhole device in a wellbore, that includes a cable head configured to connect with a cable in communication with surface equipment. The cable head is connected with a tractor module. A communication module is connected with the tractor, and a release device is connected with the communication module. The release device is connected with an anchor. The anchor section is connected with a downhole device. The downhole device is configured to communication with the communication module when the communication module is released from the release device.

A well tool for removing metal debris from a well bore has a magnet element, an anti-torque anchor, a debris removal unit, a debris container and a first connecting end for a rotatable well string. The magnet element has a cylinder-shaped housing. The removal unit has a helix-shaped longitudinal guide element arranged on the housing. The anchor is connected to the housing or the guide element such that actuation of the anchor during use will prevent rotation of the housing or the guide element, respectively, relative the well-bore. The container has an opening at the end of the housing. The housing and the guide element are rotatable relative each other, and configured such that metal debris accumulating on the housing during use is guided by the guide element towards the opening of the container when the anchor is actuated and the first connecting end is rotated.

A wireline conveyed, gas driven setting tool configured to set downhole tools including, without limitation, frac plugs, bridge plugs, cement retainers and packers. The setting tool is functioned by selectively igniting a power charge inside of a firing head. As the power charge burns, it generates gas that acts upon a piston area to stroke the setting tool. A dampening media, as well an optimized flow area at or near the distal end of the setting tool, act to slow the setting stroke.

An ingress-barrier assembly for use with pressure-operated downhole equipment can be used to limit hydraulic fluid flow in a wellbore environment for completions and operations through the life of a well. An assembly can comprise a first port to communicate hydraulic fluid with a first fluid conveyance line. The assembly can include a second port to communicate hydraulic fluid with a second fluid conveyance line. The assembly can further include a first-end stop, a second-end stop, and a moveable seal. The moveable seal can move within a bore of the assembly between the first-end stop and the second-end stop to communicate pressure between the first port and the second port.
